The 2023 Topps Chrome Black Base Set Brett Baty Purple Mini Diamond #18 is a Baseball card (Purple Mini Diamond parallel) released in 2023. Ungraded copies carry a market value of about $4.29.
An ungraded copy is worth around $4.29, a PSA 9 around $15.28, a PSA 10 (Gem Mint) around $40.36 and a pristine BGS 10 around $52.00. That's roughly a 9.4× premium for a gem-mint copy over raw — one of the clearest signals that condition-sensitive buyers dominate this card's market.
Is it worth grading?
The spread between raw ($4.29) and top-graded ($40.36) copies is fairly tight, so grading this card only makes financial sense for truly flawless copies — or for collectors who simply prefer slabbed cards for protection and display.
